How do you change a lighting fixture?

Answer 1

I've read some of the answers given & even I'm now confused. I have been an electrician for over 40years and haven't read so much cods in all my life.
White wire neutral? never, black wire hot whats that all about?
Cable colours have just changed, they used to be -
Live - Red
Neutral - Black
Earth - Bare
Now -
Live - Brown
Neutral - Blue
Earth - Bare
If you do decide to change the light fitting yourself, turn off the supply to that circuit, if in doubt turn the fuse board off.
Take down the old fitting, making a note of where the wires go, not all black(blue if new wiring) wires are neutral one could be a switch wire which should have red sleeving on it (brown if new wiring)., never assume that all colours automaticly go together. Take your time, mark everything and you should be Ok.

Well, first off, changing the fixture in your bathroom won't solve the leak problem. You have to go in the attic to see where the water is coming from and fix the part of the roof that is leaking first. If the water is coming in through the fan, you *may* have a problem with the ball or flap that is supposed to keep water or air from backflowing. Check that out too. And yes, you can change the fixture. If there is a large fixture in there now, you will need to remove it and end the wires in a junction box affixed to a stud or joist. Then you will need to patch the ceiling to close up the hole. Call a general craftsman to do the work. I wouldn't do it yourself unless you know what you are doing.

Tools:

light fixture
step ladder
wire connectors or wire nuts
circuit tester
electrical tape
Phillips-head screwdriver

Note:When working with electrical connections, normally the black wire is hot, the white is neutral and the bare is ground.

Steps:

1. If your fixture is wired properly and there's no question about which wire is hot, neutral, and ground, then begin by turning off the power at the breaker.

2. Loosen the screws on the light fixture (figure C) and remove the wires. Put the old fixture aside.

3. Next you'll install the mounting bracket, securing it with the screws that held up the old light fixture (figure D).

4. Connect the white wire in the ceiling to the white wire in the light fixture (neutral to neutral) by twisting the ends clockwise and then screwing the wire nut on clockwise.

5. Then connect the hot wire in the ceiling to the hot wire in the fixture (black to black) and secure it with a wire nut.

6. Finally connect the ground wire from the ceiling to the fixture's ground wire (ground wires are the bare copper-looking wires) and secure them with a wire nut (The ground wire nut might be slightly bigger than the other two.)

7. Next insert the long screws used to suspend the new fixture. Different lights may go together differently; follow the manufacturer's instructions with your light.

8. Slip the fixture into position over the screws and turn it so that the screw heads slip over the key holes and hold the fixture into place.

9. Tighten the screws holding the fixture into place so that its firmly in position and not moving around, yet not so tight that you break the fixture.

10. Screw the light bulb into the fixture and then screw in the rod that holds the globe in place. Secure it with the finial screw or other end piece that came with it.

11. Turn the power back on at the breaker and test your new light fixture!

Answer 5

There are just screws or decorative nuts hold that fixture to the ceiling. Take these loose and then the fixture will come down. Take loose the wire nuts, white to white and black to black. I usually turn the light on and then turn the circuit off at the breaker. If you just turn off the light switch someone may not have installed it right and it may just shut off the neutral, that would leave you with the hot black wire where you have just exposed by removing the wire nuts.

Answer 6

Turn off power to fixture at panel box. Use masking tape, and a sign to warn others not to turn power back on, at the panel box.
Disassemble the old fixture. Remove old wire nuts. Wire new fixture to building using new wire nuts, white to white, black to black, and bare to green (or bare).
Reassemble new fixture. Screw in bulb. Turn on power. Remove sign. Open cold beer. (note this step is best done last..not first)

Answer 7

turn off the main breaker to your house. i would cut it off at the pole outside.if you live in a apartment were this is not possible you need to find the breaker box in you house .find the one that says MAIN or turn them all off. do not try to replace a light if your not sure about the power being cut off. once the power is off unscrew the old fixture and let it hang down to get to the electrical wires.unscrew the wire nut off the black wires, this is your hot and the one that will shock you. once the nut is off pull the wires apart and put the nut back on the black wire that comes out of the ceiling.now you have no electricity to your old fixture. now undo the white which is neutral. now the ground which is green coming from fixture and connecting to copper from the ceilng.both wires green and copper go together. ok your light is ready to be laid off to the side. now just hook up the new one like you took down the old. be sure to put wire nuts back on your connections and wrap electrical tape around the nuts to make sure they are completely covered and wont pull apart. when your light is secure to the ceiling turn your power back on and enjoy your new light

If it's a first time thing for you and you have no one to show on the spot DON'T DO IT IT CAN BE VERY DANGEROUS and even kill you. The mechanics given to you by other persons answering your question are sincere and well intended as well as most informative but a first timer should do it with an experienced person to guide them. Good luck to you in learning basic wiring its really a very handy thing to know.
